Lee DeForest may have invented the vacuum tube but unlike him, you can actually explain how it works! Well done Don!

Very nice old tube you have there. Is the tube still operating?

Yes the filament is good. Thanks, and your welcome.

I'm looking at a 12AX7 datasheet with nine pins. What is the distinction between "cathode" & "heater" pins? Which one of these pins represents the "filament"?

The first triodes have a filament, control grid, and a plate. The filament is heated so that it can emit electrons. The control grid controls the electron flow between the filament and the positive plate. The more negative the control grid the less electron flow. The triodes with a cathode. Now the filament is just a heater. The heater heats the cathode so it can emit electrons. The control grid and the positive plate functions as before. 12AX7 nj7p.org/Tubes/SQL/Tube_query.php?Type=12AX7 Please download my free ebook.

It amazes me that the tube is (practically) a century old, and looks perfectly useable :) Do they always invert the signal?

Yes. A single stage Vacuum Tube output at the plate or Transistor output at the collector, will have a 180 degree phase shift between the input and output. Audio Phasing, Important and Useful kzread.info/dash/bejne/npuLrqWAZdnNZcY.html
